In [[X-ray crystallography|crystallography]], '''uncertainty''' in the positions of atoms increases with '''disorder''' in the protein crystal. Disorder may have two components, static and dynamic. [[Resolution]] represents the average uncertainty for all atoms. In contrast, the ''temperature value'' (also called ''temperature factor'' or ''B factor'') quantitates the local uncertainty for each atom. A high temperature factor reflects a low [[electron density]] for the atom, and ''vice versa''. The temperature value is recorded in the [[atomic coordinate file]]. In the [[PDB format]], it is the last numeric value (columns 61-66) in each ATOM and HETATM record. | |||
